Because the Changsha-Pingxiang section of the Changchun-Jiangxi high-speed railway has not yet been determined, there has been no scientific research approval. Here I refer to three papers of the Fourth Railway Institute and analyze what the recommended final route may be.

Let's start with Changsha. In fact, the North Third Ring Road Scheme has been considered before, but it is too close to the commercial and residential areas, and there are some public opinions.

In the research on the route scheme of Chang Gan Railway from Changsha West to Huanghua Airport, there are four schemes: along the North Third Ring Road, along the North Second Ring Road, along Mingxing Road and along Liuyang River.

So the North Third Ring Road should be affirmative. In order to solve the problems mentioned above, there should be a sound insulation device.

? Then the next question is that Pingxiang site has been confirmed. In fact, Pingxiang always wanted to stand in the north of Pingxiang, so the original Pingxiang planning only included Pingxiang North and Pingxiang West. The conclusion of the article "Study on the Scheme of Introducing Chang Gan Railway into Xiangxiang Area" is as follows:

The disadvantage of Pingxiang North is that it is too curved. In the latest "Research on the Overpass Setting Scheme of Changsha-Zhuzhou-Xiangtan Hub in Xiamen-Chengdu Passage", it is considered that Pingxiang North can ride across, and only the connecting line of Chongqing-Changsha-Shanghai is available.

? This connecting line plan will integrate Pingxiang North, Xiangtan North, Zhuzhou South, Liuyang and Huanghua airports into the satellite nodes of Changsha, and consolidate Changsha's hub position. Pingxiang is likely to lose the opportunity to fight side by side, and riding across becomes the last plan. Recently, the balanced high-speed rail was suddenly thrown out in Nanchang regional transportation planning (see my Pingxiang high-speed rail game on this topic for details), which is somewhat subtle in combination with riding across Pingxiang North. If Pingxiang North finally joins the station, the Gao 'an-Shangli-Pingxiang North-Hengyang line does not conform to the direction of Pingxiang North's joint station. Pingxiang North Span, from Pingxiang North Chongqing Xiachang leads to balanced high-speed rail, and the direction will be consistent. Therefore, Hunan and Jiangxi provinces may play a game on this issue. In order for Jiangxi to recognize Pingxiang's plan of riding north, Hunan had to accept balanced high-speed rail. Of course, this is just my guess, and readers can distinguish right from wrong by themselves.
